Various machines and devices have previously beer'i' made to relieve pistons but all so far made require too much time to relievepistons;

Ourinvention provides a machine wherein the relieving is done automatically and all an operator 3 needs to do isto take a relieved piston out of the machine and to place an unrelieved piston into the machine while the machine relieves other pistons therein. I v v v I H The machine illustrated relieves both sides of one piston but it appears'to be quite obvious that the same machine with suitable modifications can be built to relieve two or more pistons on both sides at the same time and; likewise, can perform machining operations on other articles with suitable modification of the machine. V

The machine specifically showh'in the drawings will now be described.

The base and table- Thebase or bedA rests on afiocr' and isof sufficientheight to bring the'top of the table B to a convenient" height for convenient operation and has the column part AI at the rear thereof.

The annular member ID, Fig. 3, is secured to the top'of the base and has the taper bore H. The annular member i2 is secured to and centralized on the member I0 and has the taper bore l3.

The table B has oppositely tapered sides fitting to the bores Hand l3"a'nd is centralized thereby. Theannular flange I4 is securedto the table and vertically covers the joints between the base and. the'm'embers ill and I2 and table.

The table shaft or spindle C has the table keyed thereon at 6 and has the part I! journaled on the bearings It in the base. The end thrust bearing I9 is adjustable longitudinally of the table shaft by means of the adjusting screw threaded into the base and supporting the table shaft endwise.

The table 3'', in this instance; has three stations or pistonsholding or locating means thereon. Each of these stations has the taper member 22, Fig; 6, to receive and centralize pistons and also has the shaft 23 extending down into the table and the flange 24 on the upper end thereof.

Each of the stubs 25 is separate from the shaft 23" and has the flange 26 on'the lower end thereof to contact the flange 24 with the locating dowel pins 21 between the flanges so that the stubs can be removed and replaced with other stubs suitable for differentpistons; Each of the taper members'22 is also rernovable to be replaced by different' locating means for different pistons. The upper end of the stubs have the grooves 28 to receive a: pin suitable to these grooves and the wrist pinb'ore in the piston to" hold the pistons against rotation thereof.

The flanges 29 inclose the working parts of the piston locating mechanism and the pins 30 in the below described bars 3! operate in the grooves 32 formed by the walls 32a and 32b to move the below describedlrelieving' means toward and away from the pistons to relieve pistons where desired and not relieve them at other places. The walls 3 2a"and32b do not extend all the way around the flange 29 so that thepin'30 will clear the'walls 32a. and 32b during'indexing of the table. The outwardly inclined surfaces 32c'and 32d tend to lead the pin 30intothe groove 32;

The table and its operating'means The table B is keyed onto the shaft or spindle C and rotates" therewith. The sleeve D is journ'ale'd" on the spindle C, Figs. 3 and. 5, and has thespu'r gear 33, the spur gear 34; and'the worm wheel 35.

The gear 33 mesheswith the gears 36 k'ey'ed oritothe pisten" rotating. shafts 23. The gear 34 meshes with the gear 37 (Fig. 5) keyed onto the below described shaft 38.

The table driving motor E, Fig. 9, is mounted in the part Al and the armature shaft thereof is coupled to the shaft 39 by the coupling 40 and has the Worm 4i thereon meshing into the worm wheel 42 normally rotatable on the shaft 43.

The speed change gear 44 keyed onto the shaft 43 meshes with speed change gear 45 keyed onto the shaft 46 which extends forwardly and into the bed or base A below the table.

The worm 4? is keyed onto the shaft 46 and meshes with the worm wheel35 on the sleeve D.

The clutch mechanism, Figs. 2 and 9, here comprises the cross-sectionally half round key or member 48 disposed in the round bottom groove 49 in the shaft 43, and having the lever 56 thereon to. rotate the member 48 in the groove and thereby bring, the half round part of the key out of the groove and into driving relation with the worm wheel 42.

When the key is in the position shown in Figs. 2 and 9 and the motor E is started, the worm wheel 42 merely rotates on the shaft 43. When the key 48 is rotated in the groove by means of the lever 5|], one edge of the half round part of the key will rise out of the groove and engage the worm wheel 42, the shaft 43 will then rotate and will rotate the shaft 46 through the change gears thereon and will rotate the worm 41.

The worm 41 will then rotate the sleeve D through the worm Wheel 35 so that the gear 33 will rotate the gear 36 and the shaft 23 and the piston thereon.

. The gear wheel 34 will rotate the gear wheel 31, Fig. 5, and the shaft 38 and the index member HS connected therewith.

The gear wheel 5! is keyed onto the spindle C and meshes into the gear wheel 52 keyed onto the shaft 53 and secured to the grooved index member 54. The roller 55 is guided in the grooves 55 of the member 54, Fig. 3 or 8. The supporting pin for the roller is driven into the bottom of the circularly grooved member 8 located 1 just above the member 54.

There is a continuous and direct drive from the sleeve to the piston station to rotate the pistons, to the shaft 38 to operate the indexing means, from the indexing member on the shaft 38 to the grooved indexing member 54 through the roller 55, and from the gear 52 on the groove member 54 to the gear 51 on the spindle C. In view of this interconnection, all elements must move in unison.

The control means The shaft 5'! is longitudinally movable and guided in the base A and has the handle 58 on the upper end thereof and the pin 59 near the lower end thereof.

The bell crank lever 69 is secured to the shaft 6| journaled in the brackets 62. I

The rod 63 is adjustable lengthwise and has one end thereof pivoted onto the shorter leg 64 of the bell crank lever and the other end thereof extends backwardly and is pivoted at 65 to one leg of the bell crank lever 66 which is pivotally supported in the base. The end of the shaft 63 is slotted at El to provide cut out clearance.

The shaft 68 is pivoted onto the end 69 of the bell crank lever 66 and extends into the compartment Al and up the lever 50 tooperate the clutch.

The bar 19 has one end thereof pivoted on the leg H of the lever 66 and is slidable longitudinally in the bracket 12. The bar 13 is pivoted onto the slidable bar 79 at 14 and carries the roller 75 at one end thereof and has the notch 16 at the other end thereof to engage the pin 11 so that, normally, the roller travels in the groove .18 and lets the motor E rotate the mechanism.

When the handle 58 is moved upwardly, the bar 63 moves forwardly and moves the end H of the bell crank lever 66 to the right as viewed in Fig. 8 and thereby separates the lock between the bracket 92 and the table has three suitablyspaced bushings 83 thereon to receive the end of the index pin 8i when one of the bushings is opposite the same.

The lever 84 is pivoted to rock on the pin 85 and has the gear teeth 86 on one end thereof engaging corresponding teeth on the pin BI and also has the roller and pin 8'! on the other end thereof in contact with the cam 88 which is so formed that the lever 84 moves the pin 8| out of the bushings 83 at the start of table indexing movement and into the bushings at the end of table indexing movement.

The cutter and operating mechanism There are two piston relieving tool means F and G on the top of the machine opposite the two rear stations H and I. The third station J, the one in the front, is the loading and unloading station (Fig. 1).

Both of the piston relieving means are shown as substantial duplicates of each other and each comprises: 1

The tool or cutter 90 (Fig. 6) is mounted on the shaft or spindle 9i journaled vertically in the head K. The worm wheel 92 is keyed to the spindle 9! to rotate the same and meshes into the worm 93 which is keyed to the shaft 94 journaled horizontally in the head K.

The shaft 94 extends through the head K' and has the keyways 95 in the outer end thereof.

The two step pulley L is splined onto the outer 0 end of the shaft 94. These pulleys are grooved for round or V belts 96 although other belt means or equivalents can be used.

The pulley M lines up with the pulley K and is keyed onto the armature shaft 9? of the motor N so that rotation of the armature shaft will rotate the shaft 94 and the spindle 9i and the cutter thereon.

The housing 0, containing the motor N, is adjustably mounted in the vertical slide 98 on one side of the block P extending from the column Al for such purposes as tightening the belts and the head K is mountedin the horizontal slide 99 on the other side of the block P for movement of the head by the bar 3!.

The bar 36 is individually slidable on the head F for adjustment of the cutter in relation to the piston Q and the bolts I09 hold the casing O tightly to the block P while the screws l 95, passing through the elongated slots 92 hold the head and to a desired distance around the piston as four invention as shown and described nor to the .the piston is rotated by the gears 33 and 36.

' The adjusting screws I03 are threaded into the block P for vertical adjustment and the threaded member I04 engages the hinge pin I05 to hold the motor supporting block I 06 in position.

The piston steadying means The piston steadying means, as shown, comprises:

The bracket I01 keyed onto the shaft C and having the three duplicate arms I08 pivoted thereon by means of the pivot pins I09. The

studs IIO are provided to afford adjustment for the arms to adjust the piston steadying members or centers I I I laterally into correct relation to the axis of the shaft 23.

A hand lever H2 is pivoted onto each of the arms by means of the pivot pins H3 and has a polygonal eccentric end II4 to abut the head I I5 f the member III to lock the same in piston steadying position. The spring IIB abuts the .head H5 and the member III and normally forces the center-like lower end thereof into contact with the usual center holes in pistons :and thereby steadies the piston.

Operation When the arms I08 reach the loading station due to the rotation of the shaft C as explained above, the operator pulls the hand lever II2 toward himself and thereby rotates the polygonal end II4 so that the face II'I contacts the head I I I5 and the spring and the center is released for removal and insertion of pistons; the position of the handle in piston releasing position is shown in dot and dash lines in Fig. 10.

After a new piston is inserted into the machine, the operator pulls the handle 58 upward whereupon the bell crank lever and the mechanism connected therewith is moved to start rotating the table for indexing as is explained above to move the pistons to new stations.

3 The sleeve D and the gears 36 keep on rotating and rotate the pistons at the stations H and I. The bars 3I are moved by the rollers thereon ;engaging the walls 32aand32b of the grooves 32. to move the cutter into and out of contact on one side of the piston at station H and on .one side of another piston at station I so that, after indexing the table, the cutter of the relievstation J for removal thereof and insertion of a new piston so thateach indexing of the table produces a relieved piston in an automatic manner.
